Got an issue on a 4.6.00 release where all existing user accounts fail to login and no new accounts will register.  Admin and Host accts. fail to work also.  I have not changed anything with this instance as, its a customer's live site.  I had planned an upgrade whenever 5.0+ became stable.

Any ideas?

For existing users: "Login Failed, remember that Passwords are case sensitive"

For new registrations, the signup form reappears with signup info populated.

Ran the install script again.  No longer getting the error in the last post.  However, I still have the same issues as with the previous version before the upgrade.

Thought I'd try the "Regain Host Password" instructions but, I'm unable to register any new accounts or login with the host account.
